South Central College MATH 115 Concepts in Mathematics Course Outcome Summary Course Information Description Total Credits 4.00 Total Hours 64.00 Concepts in Mathematics is a general education survey course designed to spotlight the field as an important component of our cultural heritage. It introduces a broad range of topics from classical as well as modern mathematics. The emphasis is on problem solving and developing the logical skills to successfully defend solutions, while at the same time showing how mathematics is a creative human endeavor influencing how we perceive the world. Among the major topics considered are logic, set theory, axiomatic systems, number theory, number systems, analytic geometry, algebra, combinatorics, and elementary probability.
